Systems and methods for peer storage devices to share host control data are described. Storage devices may include a host interface configured to connect to a host system and a control bus interface to connect to a control bus. Peer storage devices may establish peer communication through the control bus interface to share host control data, such as access parameters for host resources allocated to peer storage devices. A storage device may access host resources using access parameters allocated to that device, receive peer access parameters from a peer storage device, and access host resources allocated to the peer storage device using the peer access parameters. For example, a storage device may use a peer host memory buffer to store buffer data prior to releasing the host memory buffer allocated to it.
Legal claims defining the scope of protection, as filed with the USPTO.
9. The system of claim 8, wherein the buffer redundancy service is further configured to recover, using the first set of access parameters and the second set of access parameters, buffer data from the second host memory buffer to the first host memory buffer.
